`Divider`¶

Separate adjacent groups with a semantic horizontal or vertical rule.


Import	`from hedron import Divider`
Distribution	`hedron`
Backend activity	No
Normal render mode	`RenderMode.FRAGMENT`

Live demo¶

OverviewActivity

The preview is a local docs simulation (not a running Hedron server). Interactive demos show a “Simulated HTMX” trace when applicable.

Basic use¶

from hedron import Divider, Inline, Text

component = Inline(Text('Overview'), Divider('vertical'), Text('Activity'))

Compose under Page for full documents, or return from a fragment route for HTMX swaps.

How it works¶

A horizontal divider emits <hr>. A vertical divider emits an element with role=separator and aria-orientation=vertical, allowing the theme to size it for inline layouts.

This component's core behavior is server-rendered HTML and does not require a browser runtime. The preview is ordinary semantic HTML, so keyboard, form, link, and disclosure behavior comes from the platform.

Constructor and parameters¶

Divider(orientation='horizontal')

Parameter	Type	Meaning
`orientation`	`'horizontal' \| 'vertical'`	Separator direction.

Composition and backend behavior¶

Keep Divider at the smallest semantic boundary. Fragment routes should return only the replaced region and preserve stable target IDs across success, validation, empty, loading, and error responses.

This component is primarily presentational; keep any mutation on an explicit action or component route.

Accessibility¶

Use a divider only when the grouping is not already obvious from headings or whitespace.

Security¶

Escaping and SafeUrl / TrustedHtml are framework concerns; authorization and data exposure remain application code. Redact secrets before rendering.

Common mistakes¶

A vertical separator needs a layout that gives it visible height.
Do not copy docs-preview JavaScript into an application server.

Testing¶

from hedron import RenderMode, render

result = render(component, mode=RenderMode.FRAGMENT)
assert result.html
assert not result.diagnostics
